Nope. Every model is slightly different.
The wagons have different suspension mounts from the sedan to accomodate the different fuel tank.
The 9c1's have shorter axle shafts to allow the use of snow chains without hitting the inner fenders.
The L99 cars have a 7.5" rear instead of the standard 8.5".
The SS and 9c1's have disk brakes as oppossed to the standard drums.
If any of that is confusing then just remember that the ss and 9c1 rears are good and the rest suck
